While most parts of the FDA Food Code geared toward industry might give woodturners something to think about whether making stuff for their own use or selling. JMHO there is no food safe finish for wooden items other than straight Tung , Walnut, or laxative mineral oil. Do not agree that finishes fully cure they are food safe.

FDA Food Code 2017

https://www.fda.gov/downloads/Food/GuidanceRegulation/RetailFoodProtection/FoodCode/UCM595140.pdf

4-101.17 Wood, Use Limitation found on page 145
(A) Except as specified in ¶¶ (B), (C), and (D) of this section, wood and wood wicker may not be used as a food-contact surface.
(B) Hard maple or an equivalently hard, close-grained wood may be used for:
1. (1) Cutting boards; cutting blocks; bakers’ tables; and utensils such as rolling pins, doughnut dowels, salad bowls, and chopsticks; and
2. (2) Wooden paddles used in confectionery operations for pressure scraping kettles when manually preparing confections at a temperature of 110°C (230°F) or above.
(C) Whole, uncut, raw fruits and vegetables, and nuts in the shell may be kept in the wood shipping containers in which they were received, until the fruits, vegetables, or nuts are used.
(D) If the nature of the food requires removal of rinds, peels, husks, or shells before consumption, the whole, uncut, raw food may be kept in:
1. (1) Untreated wood containers; or
2. (2) Treated wood containers if the containers are treated with a preservative that meets the requirements specified in 21 CFR 178.3800 Preservatives for wood.

Big reason oppose to using comercial finishing or homebrew finishes is chemicals in the fnshing material, and solvents and thinners. Best advice often given today is select a low or 0 VOC finish for your project. The more you delve into low or 0 VOC finished government standard not truly enforced or reliable.

Big reason only use close-grained woods, with either mineral oil or no finish on items I turn has lot to do with what Jonathan Binzen says in his article and my own research. Could not find any wood finishing product or chemical ingrediates on any CFR. Not saying you cannot find them, just that I could not!

Many will not agree no finish pretty much okay for some turned items like rolling pins, scorrps, or spoons that’s okay too! Mineral oil easy to re-apply when needed on bowls or other turned items just fact.

Know, I’ll never in the argument over whether or not wood finishes are food safe when fully cured.

Only problem with that product is the price! How could you go wrong with carnauba & vegetable wax, and walnut oil.

All the Walnut finishing oil products come from salad food oil industry whether talking about DR’s, or Mahoney’s and others.

Frist time heard of the product thanks for posting!
